I went down a cauliflower rabbit hole after I saw these. The orange one gets its color from extra beta-carotene, the green one is basically a broccoli cauliflower, and the purple one’s color comes from anthocyanin, a phytochemical that’s commonly found in fruit and vegetables.

If you’re out shopping and see new products, snap a picture of them, and send them in via an email (theimpulsivebuy@gmail.com) with where you found them and “Spotted” in the subject line. Also, if you want to send in photos and are wondering if we’ve already covered something or if they’re new, don’t worry about it. Let us worry about it.
